Definitions

  • the present invention aims at a device for closing beverage cans, after being opened.
  • the present invention relates to a device for closing cans, of the type in which the upper base is provided with a die-cut lid, delimited by a weakening of the material that forms the upper base, to constitute a liquid outlet opening, and an opening lever.
  • This lever comprises a ring, which constitutes a first arm of the lever, a tongue, articulated to the ring by a hinge formed by a weakened portion of the material constituting the opening lever itself, and a projection, which constitutes a second arm of the lever and that is projected on the mentioned die cut cover.
  • the opening lever is attached to the upper base of the can, by means of a rivet on which the assembly of the opening lever can rotate, all this so that the opening of the can is carried out by means of the irreversible tearing of the edges of the die-cut lid, exerting on it a pressure towards the inside of the can, through the projection, when pulling with the fingers upwards of the hoop, being then defined the opening for the exit of the liquid and being the top / 36795 PC 17ES97 / 00075
  • This lever in turn comprises the ring itself, which constitutes a first arm of the lever; a tongue, articulated to the ring by a hinge formed by a weakened portion of the material constituting the opening lever itself; and a projection, which constitutes a second arm of the lever opposite the ring, which is projected onto said die-cut cover.
  • the opening of the can is carried out by pressing said lid downwards by means of the second lever arm and introducing it inside the can, to which it is supported.
  • beverage cans suffer from the implicit drawback of the fact that the tearing of the lid is irreversible. Indeed, once the can is opened, its contents are not protected from the outside, with which air penetrates into it, which causes the rapid deterioration of the properties of its contents, especially if they are carbonated or sparkling beverages, such as beer . This forces you to consume your content in a certainly limited time. In addition, when the can remains open, when it is transported it is easy to pour its contents, a circumstance that produces some uncomfortable consequences.
  • the Spanish utility model U 9002436 describes a cap for the sealing of containers, of those constituted from a metallic sheet material, such as a can of beer or soda, provided with disposable closing means, comprising an element of manipulation to achieve its closing or opening.
  • This plug has the disadvantage that its constitution and manufacturing process are complex and therefore expensive.
  • the Spanish utility model U 9301526 protects a device for the transport and consumption of refreshing beverages packaged in cans, which is composed of a circular cap that fits the upper edge of a conventional can, with a hole plug of exit of the drink, of simpler constitution than the object of U 9002436, although it presents the disadvantage with respect to the latter of being more voluminous.
  • the present invention provides a new device for the sealing of beverage cans, after being opened.
  • the first part of the cap comprises a perimeter skirt, provided in turn at its lower end with a continuous flange, which projects outwardly, so that, once the plug is inserted into the opening, the skirt exerts a pressure against the edges of the opening and the cap is retained inside the opening by the action of the tab.
  • the fixing means of the plug to the opening lever are constituted by a hollow appendix, arranged at one end of the plug and provided with a through hole, the hollow appendix adapted to receive in its inside the tongue, so that the hollow appendix can rotate in solidarity with the latter, and the through hole intended to be traversed by the rivet as well as the tongue of the opening lever.
  • the means for fixing the plug to the opening lever are constituted by a sheath, practiced without solution of continuity with the skirt and destined to receive inside the ring, which is introduced into it by an opening arranged in a longitudinal end.
  • the fixing means of the second part of the plug to the opening lever are constituted by a flat appendix, provided with a through hole essentially centered on said flat appendage, and by lateral vertical projections, essentially parallel to the lateral edges of the tongue, separated from each other a distance slightly greater than the width of said tongue and arranged on both sides of the through hole, all so that the projections serve as elements of drag of the plug when the edges of the tongue are supported, in the rotation of the plug, against said projections, whereby the plug rotates in solidarity with the tongue, dragged by it in its turn around the rivet that crosses the second part of the plug through the through hole thereof.

  • cans 1 which, as shown in Fig. 1, are constituted by a cylindrical body 20, provided with an upper base 2 and a lower base , not represented in the drawings.
  • can 1 is made of a metallic sheet material, of low thickness.
  • the upper base 2 of the can 1 has a lid 3 preformed by die-cutting, delimited by a weakening of the material that forms the upper base itself 2.
  • This also comprises an opening lever 5, whose two power and resistance arms are respectively constituted by a ring 6 and a projection 10.
  • the theoretical fulcrum of said lever 5 is constituted by a hinge 9 formed by a weakened portion of its own constituent material.
  • the projection 10 is arranged on the cut-off lid 3.
  • the opening lever 5 is connected to the upper base 2 of the can 1 by means of a rivet 12, on which can rotate the opening lever assembly 5.
  • the said rivet 12 crosses a tongue 8, which is also a constituent part of the lever 5.
  • the opening of the can 1 is carried out by pulling up the ring 6, with what the lever 5 rotates, according to a horizontal axis rotation, on its fulcrum hinge 9, so that the projection 10 presses in the opposite direction, that is downwards, to the die-cut cover 3 until the edges are torn die cut - Lu ⁇ the lid 3 and this is inserted inside the can, in an irreversible way, being defined an opening 4 for the liquid exit.
  • the device for the closure of cans object of the present invention comprises a plug 13, of flexible and elastic material, formed by two inseparable parts, of which the first part constitutes the cap itself and, seen in plan, is essentially equal to that of the periphery of the opening 4. This first part is adapted to fit in the opening 4, closing it.
  • the second part of the closing device is constituted by means for fixing the plug 13 to the opening lever 5.
  • the first part of the plug 13 is advantageously provided with a perimeter skirt 14, provided in turn at its lower end with a flange. 15, which projects outwards along the entire periphery of the skirt 14.
  • Figs. 2, 7 and 8 show in particular a first embodiment of the device for closure of cans 1 according to the invention, wherein said fixing means comprise a hollow appendix 16 disposed at one end of the cap 13, without continuity solution therewith and provided with a through hole 18.
  • the hollow appendix 16 is intended to accommodate in its interior to the tongue 8, so that it can rotate jointly with it and, consequently, with the opening lever assembly 5.
  • the rivet can be passed 12 simultaneously through the tongue 8 and the through hole 18, so that the plug 13 is attached to the opening lever 5.
  • the cap 13 comprises a sheath 17 in continuity with its skirt 15. At the rear end, the cap 13 has a mouth 19, delimited by the flexible constitutive material of the cap 13 itself, by which it can Fit the ring 6 tightly and with minimal effort. Once this operation has been carried out, the ring 6 is firmly held by its periphery by the action of the skirt 14.
  • the way of closing can 1, in order to preserve its contents or to prevent it from being spilled, is very simple. Indeed, from the position of the open can 1, in which the ring 6 is in the opposite position to the opening 4 (Fig. 4), the closing position of the device is acquired by turning the opening lever 180 degrees above the fastening rivet 12, as shown by arrow F of Fig. 5. This Fig. 5 shows the closing position of can 1, in which the stopper is just above the opening 4. Once this closed position is acquired, simply push the stopper 13, integral with the lever 5, towards the inside of the can 1 until it is fitted by its skirt 14 inside the can 1 and retained by action of tab 15.
  • Fig. 9 it can be seen in detail that the cap 13 is fixed in the opening by action of the flange 15, sealing the beverage outlet of the can 1.
  • both described embodiments of the closure device object of the invention although they allow a tight, effective and convenient closure of the beverage cans, the hollow appendix of the first embodiment and the cover of the second form In this case, they necessarily determine additional coupling operations with the tongue and the ring, respectively.
  • another embodiment of the device has been thought of, in which the second part 30 of the plug 13 is provided with fixing means of the plug 13 to the opening lever 5 of the can 1, constituted by a flat appendage 22, provided with a through hole 27, essentially centered on said flat appendage 22, and by side projections 23 and 24, arranged parallel at the lateral ends of the flat appendix 22.
  • the separation distance between both projections 23 and 24 is somewhat greater than the width of the tongue 8 of the opening lever 5 of the can 1, whereby the flat appendage 22 of the plug 13 is thus adapted to receive the tongue 8 tightly between said projections 23 and 24.
  • the plug 13 is mounted with its flat appendage 22 interposed between the upper base 2 of the can 1 and the tongue 8 of the lever 5 and with the rivet 12 arranged coaxial of the through hole 27, the lever 5 and then being held together cap 13 to can 1.
  • the projections 23 and 24 exert the function of drag element of the plug 13 when turning the tab 8, whereby the plug 13 can rotate in solidarity with the tongue 8, dragged therein in its turn for closing or opening of can 1.
  • the first part 29 of the plug 13 comprises a peripheral annular rib 7 of very low height, of the own constituent material of the plug 13 and disposed at a certain distance from the perimeter edge 21 of the first part 29 of the plug 13.
  • a cantilevered peripheral portion 11 is delimited, which is flush with the upper part of the first part 29 of the plug 13. This can be seen in particular in the Fig. 2.
  • the contour of the annular rib 7 coincides closely with that of the opening 4 of the can 1 and, as a result, when the plug 13 has been inserted into the opening 4 of the can 1, closing it, the annular rib 7 exerts a pressure against the edges 28 of said opening 4, with that said closure of the can 1 is substantially hermetic, preventing the accidental spillage of its contents, when the can is closed.
  • the peripheral portion 11 acts as a stop to the introduction of the plug 13 and as a means of extracting it, since it allows it to be pulled very simply, for example, by means of the nails.
  • the lateral projections 23 and 24 are arranged on different sides of the cap 13 than the annular nerve 7, whereby the flat appendage 22 is located between the upper base 2 of the can 1 and the tongue 8, it is also possible the case in which said projections 23 and 24 are arranged on the same side of the cap 13 as the annular rib 7, the tongue being then located between the base 2 and the flat appendix 22, all within the scope of the inventive concept.
